    摘要: A method for operating a mobile terminal as access point, wherein the access point composes a network together with one or more associated client stations, wherein the access point has an operational mode of alternating awake and sleep periods, and wherein the access point broadcasts beacon frames at regular intervals for signaling communication parameters to the associated client stations, is characterized in that the access point, based on the level of activity in the network, adjusts the communication parameters by slowing down or accelerating the access of the associated client stations to the network. Furthermore, a corresponding mobile terminal is disclosed.

    摘要: For allowing a high level of performance quality within a network while reducing computational method complexity a method for operating a wireless network is claimed, wherein at least one MIMO (Multiple Input Multiple Output) group of different stations will be constructed by means of a grouping algorithm based on a grouping metric for providing a MIMO group of different stations which can be addressed simultaneously in space by a base station using MIMO techniques and meeting a definable level of performance quality and wherein the grouping metric is based on an SINR (Signal-to-lnterference and Noise Ratio) experienced by each station within the MIMO group. The method is characterized by the following steps: computing an SNR (Signal-to-Noise Ratio) that a new station would experience without any interference when added to an already existing MIMO group; computing an SINR estimate by correcting the SNR with the sum of the spatial correlations between the new station and each of the stations already present in the existing MIMO group; and using the SINR estimate for deciding whether the new station can be added to the existing MIMO group meeting the level of performance quality. Further an according network and device is claimed, preferably for carrying out the above mentioned method.

    摘要: A method of scheduling periodic processes for execution in an electronic system, in particular in a network, in a data processor or in a communication device, wherein the electronic system includes a controller for performing the scheduling, wherein a number of N processes Pi are already scheduled with each process Pi having an individual service interval Sli, and wherein an additional process PN+1 is to be scheduled with a service interval SIN+1, is characterized in that the additional process PN+1 is scheduled in such a way that the minimum time lag between the execution times of the additional process PN+1 and the execution times of the number of N already scheduled processes Pi is maximized. Furthermore, a corresponding device for scheduling periodic processes for execution in an electronic system is disclosed.

    摘要: A method for filling a WiMAX downlink frame by the base station of a WiMAX network, wherein the downlink MAC Protocol Data Units (MPDUs) are fitted into the WiMAX downlink frame by means of a DL-MAP scheduler, which allows the concatenation of downlink MPDUs from different connections in single bursts, the bursts having a rectangular shape in terms of the two dimensions - OFDMA (Orthogonal Frequency Division Multiple Access) symbols and subchannels - of a WiMAX downlink frame, is characterized in that the DL-MAP scheduler is configured in a way that it considers the concatenation of downlink MPDUs from different connections in single bursts based on the available and/or the remaining free space in the WiMAX downlink frame, such that it simplifies the DL-MAP scheduler task of filling the WiMAX downlink frame minimizing the amount of wasted radio resources.
